Are you passionate about performance?  Do you enjoy learning the ins and outs of a networked app and finding ways to make it go faster? Do you compile your own Linux or FreeBSD kernels to tweak performance to suit your goals?  Are you technical, but articulate, and excited about sharing your findings? Would you like to know that your work is contributing to a greater mission with global impact?  How would you like to do this from the comfort of your own home? Dragos has an opportunity for a Staff Quality Engineer in Performance to join our growing team of talented Engineers making great contributions to our mission of Safeguarding Civilization!  As a Quality Engineer in Performance, you will help establish networked application performance metrics for our platform and document and communicate deltas and suggestions for improvements.  You will create instrumentation that you and the team will use to characterize performance impacts of various load scenarios and you will be responsible for the design and execution of tests that simulate real-world customer scenarios, including worst-case scenarios, and come out of it with data and a path forward.  In addition, as part of a larger (and growing) quality organization, you will be responsible for helping ensure team members bake performance testing into their workstreams.
